OS backup across network

Ragni Singh — Tue, 10 Sep 2002 16:19:48 GMT

hey all,

It is possible to do a full OS backup of a server across the network. What I'm getting at is I have a server that we don't have a tape drive for. Any help is greatly appreciated. Points will be assigned.

You can do it through Ignite UX. Configure an Ignite Server and take the backup of vg00 full through network.

Hi,

You need IgniteUX, which is a great product and it is free. Here is the link for the download:

I've been backing up my disk drives across networks for quite sometime without any special utilities.

If you have a mount point on your box that you want to backup, I would use fbackup or cpio and simply exclude the mount directory.

Using the automounter, I'd mount the machine for the backup as, say myBackupFS in /net then using cpio exclude /net during the backup. For example:

cd /
find . ! -name '/net/*' | cpio -oxmB > /net/myBackupFS/myArchive.cpio

This should backup your entire filesystem, including device files, without going down the backup directory tree.

I hope this helps. If you need more info, let me know.

I use omni back to back up the full os as well as full host over network and Ignite server for bootable image on tape .

Sanjay,

If you want to place the backup on a disk on another machine with enough space, then you can use "tar" to backup your directories.

tar -cf - /* | remsh remotesystemname (cd /backupdir; tar -xf - )

If you have any other requirement than this pls specify.

One more point i would like to specify.

You may also backup other directories using their path name as /test /dbms etc

in place of /*

Sanjay,

Backing up OS files is very well handled by one of the HP's product utility "make_net_recovery" which is a part of Ignite-UX. backing up with tar/cpio will not allow you to recover the system in case you need to rebuild the system from the scratch.

Here is the link to start with :

Yet another tool for network backups on HP systems is fbackup.
You need to run rmt on the remote HP system with tape device and establish trust from the system backing up to the
one with the tape drive.
It's slower that using fbackup with a local tape drive, but it works. You can recover with frecover as well to the remote system. Good luck.
